The present invention relates to a grain thresher, and more particularly, to provide a grain thresher having a handle, a drum cover and an air blowing device which can be conveniently used when moving a grain thresher, . In order to accomplish the above object, a grain threshing machine comprises a "C" -shaped handle for gripping and pulling a grain thresher, and is configured to be able to go into and out of a guide tube formed on the right side of the grain thresher body, And a stopper for preventing the drum cover from being unnecessarily tumbled when the drum cover installed on the upper portion of the rotary drum is turned backward to open or close the rotary drum. Further, the blower configured in the lower portion of the grain- The present invention is characterized in that an air regulating plate having a handle lever for controlling the air inlet and air supply on both sides thereof is formed on the lower portion thereof and the present invention is characterized in that it is used when the grain thresher is moved to one side of the grain threshing machine The "C" -shaped handle is configured to enter and exit the guide tube of the grain thresher Which is useful when the operator uses the grain thresher or when storing the drum, and it is convenient when the drum cover installed at the upper part of the rotary drum is closed unnecessarily when the drum cover is turned backward, So that it can be conveniently used with the handle lever formed at the front side of the air regulating plate of the air blowing device constructed in the front lower part.본 고안은 곡물 탈곡기에 관한 것으로서, 좀 더 상세하게는 곡물 탈곡기를 이동시 편리하게 사용할 수 있고, 동선을 최소화시켜 편리하게 작업할 수 있도록 손잡이와 드럼커버와 송풍장치가 개선된 곡물 탈곡기를 제공하려는 것이다.상기와 같은 목적을 달성하기 위한 곡물 탈곡기는, 곡물 탈곡기를 잡고 당길 수 있도록 "ㄷ"자형 손잡이를 구성하되, 곡물 탈곡기 본체의 좌 우측에 구성된 안내관에 출입할 수 있게 구성되며, 곡물 탈곡기를 구성하는 회전드럼을 오픈, 또는 밀폐하기 위해서 회전드럼의 상부에 설치된 드럼커버를 뒤쪽으로 넘겼을 때 불필요하게 넘어가는 것을 방지하기 위한 스톱퍼가 구성되며, 또한 곡물 탈곡기의 하부에 구성된 송풍장치를 곡물 탈곡기의 앞쪽 하부에 구성하고 양쪽에 공기유입구 및 공기 공급량을 조절하는 손잡이 레버가 앞쪽에 형성된
